I added the button PAY NOW with PAYPAL on home page of http://www.carlocollodi.it and clicking on the button I receive this error message from paypal:
This recipient does not accept payments denominated in 1. Please contact the seller and ask him to update his payment receiving preferences to accept this currency.
My code is:
[PAYPAL TYPE="ADD" NAME="L'AUTORE DELLA STORIA PIÙ FAMOSA DEL MONDO" AMOUNT="9.99"]
What I have to do?
